3. Explore settings
Your first step will be to go into the settings of the app, you can choose the currency from the app settings.
The settings are on i, at the bottom right as you open the app.

The settings screen:

4. Insert a debtor
After choosing your currency, let’s start with an example of debt.
For example Paul has to give you 50€. Then this app is the only one that’s right for you

Inserting Paul like name and 50 like value, like this:
The result is:

5. Insert a creditor
Unfortunately we are not always in credit, so sometimes you have to manage our debts.
The same example, but now Paul is in credit with you 50€ (ie you are in debt with Paul)

So you can insert the minus before the value:

The result is:

6. Manage a debit or credit
This is the most important function of this app.
The BlackList allows you to not only remember, but also to add or remove money from your debit or credit.
Touching above the line that we have to change, a bar appears at the bottom with various numbers and another top bar (the bar multiplier):

As an example: at this time we gave 10$ to Paul, so our debt rises to -40$ (tap +10):

Of course, if we for example, more than the 50$ you owe to Paul, you add more 10$ debt, then we will touch -10$.
Like this:

7. Use the bar multiplier
Another important function is the bar multiplier.
It allows you to change the value from add or remove for each row, each time a number is clicked, it will check the number multiplier.
For example, if we take 30$ from the debt we owe to Paul, we can’t click 3 times +10$.
Moving the bar multiplier of 3x, touched each number is multiplied by 3. Then going to touch the +10$, the result is +30$. Exactly like this:

8. The summary
The BlackList also offers a page where all movements are recorded and saved, so as to check every time you want all movements.
Just open the app at the top right there is a button with a book, this is the summary.
In summary besides the movement, is also saved the full date of the movement itself.
